Assigned to the development of an application for business revenue accounting. The system is Client-Server based and includes
batch processes for data integration from other functions. Since business requirements were primarily accounting-focused,
I performed bug fixes and added features to the live system through consultation with subject matter experts.
In addition to development, I managed project tasks, including man-hour estimation and task management,
as well as client communication. I also handled operations such as correcting invalid data.
I identified inconsistent data from approximately 20 million records generated monthly,
using PowerQuery and internal Java tools to process and correct these large datasets.
